Quality of Dietetic Patient Education Materials for Diabetes and Gastrointestinal Disorders: Where Can We Do Better?

(1) Background: Patient education materials are frequently used by dietitians to support counselling and reinforce key concepts. No studies have examined the quality of dietetic patient education materials for diabetes and common gastrointestinal conditions. (2) Methods: Materials relating to the dietary management of diabetes and gastrointestinal conditions (IBD, IBS, lactose intolerance, coeliac disease and low-FODMAP diets) were evaluated by three dietitian raters. Readability was assessed, and materials with a reading grade level ≤ 7 were considered readable. The PEMAT was used to assess understandability and actionability. Clarity was determined using the CDCCCI. (3) Results: Overall readability scores were satisfactory with a median grade level of 6 (IQR: 5–8). Readability scores did not differ between material types (p = 0.09). The health literacy demand of materials was suboptimal, with a mean understandability score of 65.9 ± 15.1% and an actionability score 49.6% ± 20.8%. Both scores fell below the benchmark of ≥70%. These did not differ between material types (p = 0.06 and p = 0.15, respectively). Clarity scores were below the benchmark of ≥90% (mean score 64.2 ± 14.8%). Only 6.6% of materials achieved a score of ≥90. (4) Conclusions: Improvements to the health literacy demand and clarity of dietetic patient education materials are required. Areas for future improvement have been identified.
